Subject[PATCH v2] mtd: chips: Replace printk() with pr_*()
Using pr_<loglevel>() is more concise than printk(KERN_<LOGLEVEL>).
This patch:
* Replace printks having a log level with the appropriate
pr_*() macros.
* Indent the code where possible.
* Remove periods from messages.

Signed-off-by: Arushi Singhal <arushisinghal19971997@gmail.com>

changes:
Before printk() is changes to dev_*macro(), but it was not good idea
because mtd->dev is only initialized after mtd_device_register() is called.
